To all whom it may concern:

Be it known that I, FRANK L. WOLrE,-a citizen of the United States, anda resident of Medford, in the count State of Massachusetts, haveinvented certain new and useful Improvements in Thistle-Valves, of whichthe vfollowing is a specification.' j I M invention relates to whistlevalves and its o ject is to provide means for automatically o ratingsuch valvesand automatically recor mg the passa e of steam through. the`outlet chamber of t e valve into the whistle bell, and the time of suchpassage.

It isan improvement upon m invention described in Letters Patent f o.787,422 dated April 18, 1905; and also u on -another invention for whichI have app led for Letters Patent by an application filed December 1,1905 Serial No. 289 878.

` It is illustrated byA the accompanyin drawings in which- Figure 1 is avertical section of the whistle valve. Fig. 2 is a plan view'of theclock. Fig. 3 is an elevationof the electro magnet on line 3-3, of Fig.2.

Similar characters refer tok similar parts a throughout the severaldrawings. y

1 is the Whistle bell.

2 is the whistle bowl threaded-at its base for'attachment to the steam,or any other fluid reservoir and divided intotwo communicating chambers,the inlet chamber 3 and the outlet chamber 4. Seated in chamber 3 is thevalve 5 O erated by the piston 6 1ocated-in the cylinder 7 laterallprojected from the Outlet chamber 4, and having pas- 8 leading to theopen air and other passages 9 leading to the cylinder 10 laterallyprojected from inlet chamber 3. In the mlet chamber 3 is also seated thespring actuated valve 11 with its stem 12 arranged in the cylinder 10which ma be operated mechanically by the lever 13 Vulcrumed at 14 on theouter wall of cylinder 7.

Projected from the inlet chamber 3 is the cylinder 15 with a reducedinner portion 16, a larger middle portion 17 with passages 18 leadingtherefrom to the inlet chamber 3 and a still larger outer portion 19which constitutes the cylinder proper with the passage 20 leadingtherefrom to the inlet c amber 3. In the outer portion 19 of thecylinder 15 is located the balanced piston 21 having the.

lThis pistonY 21 e loosely the outer portion 19 of the cylm er 15 therebrmit the' steam from the inlet cham pe tmg round itI and p beco steam'.The valve 11 as a second valve stem 23 which asses through and is invsliding contact wit the inner portion 16 of the the piston stem 22 andiston 21,

r3tosurlandis furnished on its outer end wit the adjustabledmt. 30. Onthe valve stem l23 is arrange t e -houllders on. ti'ildlirldvell and onthe cyliner 5.

Projected from the cylinder 15 is the diahragmlchamber 26 with apassagev leading rom one to the other, through which passage extends thevalve stem 28 of the spring actuated va1ve 29 seated in said cylinder15.

Passages 24 lead from the dia hr chamber 26 to the open air. In t is'aphragm chamber are arranged the diaphragm 31 and the spring 32. Thediaphragm 31 rests upony the annular shoulder 33 in contact with theouter end of the valve stem 28, and is held in. place by the threadedProjected from'v the Outlet chamber-4 is the da hragm chamber 42 Withthe assage 43 balanced in said 25 confined between rin 34. lgrojectedfrom the diaphragm .chamber 26 lea Aing thereto from said outlet c amber4.

In the passage 43 isseated the spring actuated leak valve 44. On anannular shoulder 45 of the diaphra m chamber 42 rests the diaphragm 46'he d in place b ring 47 which engages the t readed wall of thediaphragm chamber 42. The threaded hub 48 enga es the said threaded Wallof the diaphragm c amber acting as a jam nut on the threaded ring 47.Extending through this hub 48, and in free sliding contact therewith, isthe spring actuated plunger 49 With its inner end 1n contact With saiddiaphragm 46, and having mounted in its outer end the the threadedsuccessively engage the spring 56 normally 1in contact with theadjustable contact screw l57 mounted on the insulator fiber block- 58l'mounted in said case, to which-block the wires 39, A39a lead, the wire39 being connected by the bindin nut 59 with said spring 56, a'nd thewire 39gbeing connected by the binding nut 59al with the adjustablescrew 57 whose inner end normally contacts with the 56. The wires 53,538L connect with t e e ectro magnet 64 disposed within the clock casewith its spring actuated armature 65 having an arm 66 pivoted to the arm67 iXed to-theshaft 68 mounted in the clock case, and having fixed toits up er end the pencil arm 69 carrying the pencii) 7 O andthe arm 71carrying a pencil platform 72. On the arbor 54 is mounted the rotarychart support 73 on which rests the chart 74 held in p ace by the washer75 and thumb nut 76. This chart rests also upon the annular support 77.

This device, which may be used for recording the o eration of thewhistle valve under any con itions, is particularly useful upon vesselswhere whistles are required to be sounded at certain intervals, forinstance during a fog; and the chart in the drawing is arran ed torotate once in four hours, as just state or during the usual watch onvessels. Of course any fluid other than steam may be used with thewhistle valve.

The operation of the device is as follows: The whistle valve beingattached t0 a steam boiler, steam fills the inlet chamber 3, thepassages 18 and 20, and the cylinder 15, pressin equally on the innerand outer suraces o the iston 21, the valves 5, 11, and 29 are seate thevalve stem 23 has a very slight longitudinal play so as to insure theseating of the valve 11. The valve stem 28, the diaphragm 31 andarmature stem 38 are in contact. When the electric circuit 39 39a isclosed the spring 56, being in contact with the screw 57, the armatureforces the valve 29 from its seat, compressing the spring 32 andextending the sprin 38, and permitting steam to escape from cy inder 15to the open air. The balanced piston 21 is forced by the steamoutwardly, unseating the valve l1 and compressing 'the spl-ring 25.. Thesteam escapes into the cy der 10 thence through the passa es 9 into thatart of the cylinder 7 above t e piston 6. he pressure of the steam uponthe istonbeing racticall `the same as that of t e steam in t e inlet camber, and the surface of the piston belng greater than the surface ofthe valve 5,t'lis" pressure Will force the valve from its seat and allowsteam to escape from the inlet chamber into the outlet chamber 4 andthence upward through the whistle bowl 2 into the whistle ing the'contact s rings 51, 51 into contact,

closing the electrlc circuit 53, 53", operating the pencil arm 69, andmoving the pencil upon the rotating chart 74. l

The gear 55 on the arbor 54 carries the spring 56 out of contact withthe screw 57, t ereby opening the circuit 39, 39'L and the valves 29 and11 return to their seats, forced thereto by the steam pressure assistedby the springs 25, 32 and 38. The steam remain ing in the cylinder 10,passages 9 and space above the piston `6 in cylinder 7 instantly escapesthrough the passages 8 into the open air, thus removing the pressurefrom the iston 6 and allowing the valve 5 to be force to its seat by thepressure of steam in the inlet chamber 3 5 thus cutting off the, supplyof steam to the outlet chamber 4, to the whistle bowl and to thediaphragm chamber 42, thus permitting the sprmg actuated plunger to moveinwardl and separate the s rings 51 and 51a there y opening the circult53, 53 permitting the armature 65 to return the pencil 70 to itsstarting point; and so the operation is repeated and the whistle soundedas the teeth of the gear 55 successively make and break the contact ofthe spring 56 with the screw 57 as just described. The circuit 39, 39ama be opened and closed by pressing a button i desired.
